4 Summary
USGS data services are an important resource for different communities, including organizations at the state, county, and city level. The data are used for variety of
purposes, such as scientific research, planning, and decision-support. OGC assisted the USGS by running an interoperability assessment initiative with the goal of determining
whether OGC standards as implemented in USGS servers were meeting users requirements. Three activities were part of this project:
Compliance Testing: A total number of 15 Web services were tested using the
CITE TEAM engine as well as additional manual tests. The goal was to evaluate the compliance of WFS, WCS, and SOS service instances. The current
compliance test suite requires some of these services WFS 1.0 and WFS 1.1 to serve a specific test data set. As it was not possible to load this test data set on the
production level service instances, the compliance tests were adapted to work with generic services. The type and nature of the tests have been conserved. The
modified tests and test results are described in chapter five. Future work is envisioned to make the changes official.
Developing executable test suites for CAT 3.0: At the time of this project the
OGC CatalogCSW 3.0 candidate standard was in the approval process. A test was developed for the basic conformance class and published in GitHub. This test
should serve as a baseline that can be advanced by other test developers. More details can be found in chapter six.
Development of use cases and investigation of usability with Communities of Use: Over the course of three webinars, experiences and use case descriptions
from six participants were recorded and assessed. This process yielded a broad range of use cases. Some organizations used the offered services “as is”. Other
organizations integrated data and services into their own workflows, developing complex processing chains and advertising new data sets based on data processing
results.
In summary, all participants documented use cases that heavily depend on reliable services. These services are either part of independent web applications or part of
complex workflows that in turn generate additional related data. In terms of data formats and corresponded service types, users require data to be served in multiple formats with
different service types. As an example, a number of users reported using web-mapping services for base layers within their applications, whereas other users required the same
data to be served in vector or raster formats that can be further processed within some GIS technology. The GIS tools used most often include various ESRI ArcGIS
